You two Tabulam lads need to contact the local Amateur (Ham) Radio Club -SARC in Lismore. Their web page is at;
https://sarc.org.au/
I know they have one member who lives at Tabulam and there are several members (including me) involved in building 21cm receivers with an American research group.
If you have a shortwave radio tune to 3.604Mhz 6.30am on week days NSW time.
